Yes... it has been forever since I posted anything about this project. Life and work continue to get in the way of what I consider important.
I've spent what time I can on trying to solve a little problem. I didn't like the idea of having to manually open the coin door in order to spin the CP. I just seemed like there had to be a way to automate it. So I've been working on a fix.
I just wanted to push the top of the CP away from me and rotate it into place. I'll never push down on the top, so the only time the coin door needs to move is when the CP is rotating up into place. Now that I've typed it, I get that it is hard to imagine. Think of it like this. You are standing on the left side of the cabinet. The CP will only rotate counterclockwise, never clockwise. So the coin door will tilt open to allow the CP to rotate past and then close back. I've installed these things called Blumotion, which keep the door from slamming shut. They allow it to close slowly.
I created a cam to push a cam follower out, which in turn pushes on the door and opens it. When the CP finishes it's turn, a return spring closes the coin door. That's it. But designing that cam was a pain. I had to make it out of hardboard so I could adjust it just right. Then I covered it in Bondo to try and harden up the edges. I should have used JB Weld, but hindsight is 20/20.
The cam follower is made from a piece of 1/8" thick steel with a roller blade bearing on one end and a skateboard bearing on the other held in place with JB Weld.
Here are some bad pics and an even worse video. It's bright enough in the garage to work, but to dark for good pics. And yes... I know it's dirty. I'll clean it when I'm done.
